DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of devices and methods consistent with aspects related to the invention as recited in the appended claims.

FIG. 1 is a flow chart illustrating a method 100 for presenting tasks according to an exemplary embodiment.

The method 100 for presenting tasks is performed by a terminal. The terminal can be a smart terminal which can perform multiple tasks in parallel, such as a smart phone, a tablet computer, a Personal Digital Assistant (PDA). As shown in FIG. 1, the method 100 for presenting tasks includes the following steps.

In step S101, an active index of each of tasks, which are currently in operation in the terminal, is acquired.

In the present embodiment, when a user of the terminal wants to check all the tasks currently in operation in the terminal, the user can input a task presenting instruction. The task presenting instruction can be a press on a HOME button for a predetermined time, or double clicks on a HOME button. The way the task presenting instruction is input into the terminal is not limited by these examples.

After the terminal receives the task presenting instruction, the terminal can acquire an active index of each of the tasks, which are currently in operation. An active index of a task may be a measurement of how the user operates the task. In one embodiment, the active index can be a frequency of the task being started. For example, after the terminal is turned on, active indices of all tasks are set to a default value, such as zero (0). The terminal can store names of tasks and their corresponding active indices. When it is detected that a task is started, the active index of the task is increased by one (1), to update the active index of the task. The terminal is configured to further store the updated active index of the task. The terminal can also reset the active index of the task to the default value when the operation system of the terminal is restarted.

In the present embodiment, after the terminal receives the task presenting instruction, the terminal can acquire an active index of each of the tasks that are currently in operation based on the stored data of names of tasks and their corresponding active indices. However, one skilled in the art will now appreciate that the active indices can be set through other manners. For example, an active index can be a frequency of the task being started. For example, when the terminal detects a task is started, the terminal can calculate a frequency of the task being started based on the number of times of the task being started, so as to update the active index of the task, and store the updated active index of the task.

In the present embodiment, the tasks are generally applications installed in the terminal. For example, the tasks can include an address book application or a notebook application installed in the terminal. The tasks can also include various other Applications (APP) installed in the terminals, such as Sina microblogging, We Chat, Alipay Wallet, etc.

In step S102, the tasks, which are currently in operation, are ranked based on the acquired active indices.

Based on the step S101, after the terminal acquires the active index of each of the tasks, which are currently in operation, the terminal can rank the tasks based on their active indices. For example, the tasks can be ranked according to an order from the highest active index to the lowest active index, or can be ranked according to the active indices combined with their start times. The present disclosure is not limited to these examples.

In step S103, the tasks, which are currently in operation, are presented according to the ranking result.

In the illustrated embodiment, after the terminal receives a task presenting instruction, tasks which are currently in operation can be ranked based on the active indices of the tasks, and presented according to the ranking result. The usage of the tasks can be presented with high accuracy so as to improve user experience.

FIG. 2 is a flow chart illustrating a method 200 for ranking tasks currently in operation based on active indices according to an exemplary embodiment. Method 200 can be performed by a terminal.

As shown in FIG. 2, based on the above embodiment shown in FIG. 1, method 200 includes the following steps.

In step S201, the terminal determines whether the active index of each of the tasks is greater than or equal to a threshold.

In the present embodiment, the threshold can be predetermined, for example, by a developer or the user of the terminal. A task with an active index greater than or equal to the threshold is generally a task frequently operated in the terminal, and a task with an active index smaller the threshold is generally a task less frequently operated in the terminal.

In step S202, the terminal assigns the tasks having an active index larger than or equal to the threshold to a first group of tasks.

In step S203, the terminal assigns the tasks having an active index smaller than the threshold to a second group of tasks.

In the present embodiment, after the terminal acquires the active indices of the tasks which are currently in operation, the terminal can determine whether each of the active indices is larger than or equal to the threshold. The tasks that are currently operated in the terminal can be divided into two groups: a first group including tasks having an active index larger than or equal to the threshold and a second group including tasks having an active index smaller than the threshold. It can be understood that, the number of the tasks in the first group and in the second group is a natural number larger than or equal to zero (0).

In step S204, the tasks in the first group are ranked according to an order of from a task having the largest active index to a task having the smallest active index.

Based on the step S202, when the number of the tasks in the first group is larger than one (1), the terminal ranks the tasks in the first group according to their active indices from the largest to the smallest. It can be understood that, if the number of the tasks in the first group is one, it is not necessary to rank the tasks in the first group. If the number of the tasks in the first group is zero, step S204 can be skipped.

In step S205, the tasks in the second group are ranked according to an order from the task that is started the latest to the task that is started the earliest.

Based on the step S203, when the number of the tasks in the second group is larger than one, the terminal ranks the tasks in the second group in which each task has an active index less than the threshold according to the times when they are started. In the illustrated embodiment, in the second group, a task started later is ranked higher than a task started earlier. It can be understood that, if the number of the tasks in the second group is one, it is not necessary to rank the tasks in the second group. If the number of the tasks in the second group is zero, the step S205 can be skipped.

In step 206, the first group of tasks is ranked before the second group of tasks.

In one embodiment, depending on a predetermined presenting direction, the first group of tasks can be presented before the second group of tasks. For example, when a user is viewing a screen of the terminal, which presents the tasks in a horizontal direction, the first group can be arranged on the left side of the second group. That is, the first group is arranged and presented before the second group. If the terminal presents the tasks in a vertical direction, the first group can be arranged on an upper side of the second group. That is, the first group is arranged and presented before the second group.

In some embodiments, the order in which the steps S202 and S203 are performed is not limited. For example, the step S203 can be performed before the step S202. Further, the order in which the steps S204 and S205 are performed is not limited. In some embodiments, the step S205 can be performed before the step S204 is performed.

In one embodiment, six tasks are currently operated in the terminal. Each of the tasks has an active index, as shown in Table 1, where start times of the tasks are: M1 earlier than M2, M2 earlier than M3, M3 earlier than M4, M4 earlier than M5, and M5 earlier than M6.

TABLE 1 Task Active Index M1 2 M2 4 M3 16 M4 28 M5 7 M6 12

In one embodiment, the predetermined threshold is 10. Based on the active indices of the six tasks, three tasks, M3, M4 and M6, can be assigned to the first group of tasks, and three tasks, M1, M2 and M5, can be assigned to the second group of tasks. The three tasks in the first group can be ranked according to their active indices from high to low as: M4, M3, and M6. The three tasks in the second group can be ranked according to their start times from the earliest to the latest as: M1, M2 and M5. The terminal presents the first group of tasks before the second group of tasks. The presenting order of the six tasks is: M4, M3, M6, M1, M2, and M5. FIG. 3 illustrates a terminal 300 having a screen 301 presenting a page 302. The tasks M4, M3, M6 and M1 are presented in the page 302 from left to right, and the tasks M2 and M5 are in a hidden page.

In the illustrated embodiment, the terminal can rank tasks currently in operation based on two conditions: start times and active indices of the tasks. Thereby, the tasks can be presented with more accuracy to improve user experience.

In some embodiments, the terminal can rank the tasks in the first group according to an order of the tasks from being started the latest to the earliest. Referring to Table 1 again, if the task M4 is started earlier than the task M3, and the task M3 is started earlier than the task M6, the three tasks in the first group can be ranked according to their start times as: M6, M3, and M4. The terminal arranges and presents the first group of tasks before the second group of tasks. A different arrangement of the six tasks can be obtained as: M6, M3, M4, M1, M2 and M5. FIG. 4 illustrates the terminal 300 having the screen 301 presenting a page 303.

In another embodiment of the present disclosure, the terminal can rank the tasks in the first group tasks according to an order of the tasks from being started the latest to the earliest, and can rank the tasks in the second group according to their active indices from high to low. Referring to Table 1 if the task M4 is started earlier than the task M3, and the task M3 is started earlier than the task M6, then the three tasks in the first group can be arranged according to a their start times as: M6, M3, and M4. The three tasks in the second group can be arranged according to their active indices as: M5, M2, and M1. A different arrangement of the six tasks can be obtained as: M6, M3, M4, M5, M2, and M1. FIG. 5 illustrates the terminal 300 having the screen 301 presenting a page 304. Referring to the task presenting page 304 in FIG. 5, the tasks M6, M3, M4, and M5 are presented in the page 304 from left to right, and the tasks M2 and M1 are in a hidden page. The tasks M2 and M1 can be checked by the user sliding on the screen 301 to flip the page.

In another embodiment of the present disclosure, the tasks which are currently in operation can be ranked according to their active indices from high to low. Referring to Table 1, a different arrangement of the six tasks can be obtained as: M4, M3, M6, M5, M2, and M1. FIG. 6 illustrates the terminal 300 having the screen 301 presenting a page 305.
